UNITED STATES MATHIAS FRANK MCNELLY, OF CHICAGO, ILLINOIS.

ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented Nov. 20,19o6.

Application filed November 22, 1905. Serial No. 288,615.

To LLZZ wlw/1t t may cowl/cern.

Be it known that I, MATHIAS FRANK Mc- NELLY, a citizen of the United States, residing at Chicago, in the county of Oook and State of Illinois, have invented a new and useful Improvement inAcetylene-Generators, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

The object of my invention is to provide a new and improved feeding device for an acetylene-gas machine.

In the drawings, Figure l shows a side elevationof a portion of machine with the neck thereof shown in vertical section, the internal mechanism being shown in section and the actuating rod and its mechanism being shown in longitudinal section; Fig. 2, a plan view of the feeding cup or bucket; Fig. 3, a cross-sectional view of the neck, taken on line a a of Fig. 1; Fig. 4, a top or plan view of the shelf or bracket on which the cup rests, and Fig. 5 a side elevation of the bucket or cup.

The numeral 1 shows the neck of the machine, and 2 a funnel-shaped member arranged to receive the calcium carbid from the upper chamber and direct it into the cup or bucket 5, the numeral 3 showing a system of wires bent over the funnel-shaped member to pre vent the whole weight of the carbid from pressing into the funnel-shaped member and packing the carbid therein.

4 represents the operating rod passing through a stuffing-box and carrying the actuating-rod 4', which slides the cup 5 back and forth across the shelf or bracket 5 when the rod 4 is revolved. The stuffing-box is seen at 4", and at 43 is seen a rod to loosen the carbid in the eXtreme neck of the member 2 provided it becomes packed at that point. The outer end of rod 4 carries the crank 47 and passes loosely into crank 4, the lower end of said last-named crank entering socket 49 and is clamped therein, when desired, by the spring-plunger 4a, set in the casing 4S. The rod 4c enters and is fastened tightly in crank 4 and on its outer end carries a collar, which in turn carries arm 4, the end of the arm passing through an openingin the troughlike member 9', which is attached to and rises and falls with the gasometer 9 setting in the water-tank 10. The cup 5 is centrally divided by the partition 6 and has the lug 7 passing underneath the shelf 5 to prevent any separation of the cup 5 from shelf The shelf 5 has two openings through it, 57, (see Fig. 4,) and they are arranged so that as the cup is slid over to one side or the other as far as it will go the partition 6 in cup 5 will lie directly along the slanting edge of the hole it is moved toward. As cup 5 has no bottom, one half of its open bottom edge will rest over one of the openings 52, and the contents of that half of the cup 5 will fall into the generator and be converted into gas, While the other half will not be discharged until the cup is moved the other side of the shelf. In the bottom edge of the cup 5 is a small notch or opening 53, so as to allow any pieces of carbid that may get in the way to pass into this opening and ease the cup, so it will slide easily. The cup is pivoted at 8 to the shelf, so it can be swung from side to side.

The operation is as follows: As the gas is formed in the gasometer the bell or part 9 rises and carries the trough-like member 9 up with it. As it rises the arm 4 is also carried upward, and this rotates rods 4c and 4 and cranks 46 and 47, and actuating-rod 4 moves like a pendulum sidewise, making half of a pendulums stroke and carrying the cup 5 across the shelf until one-half its open bottom rests over one of the openings 52, when one-half its charge of carbid will fall into the generator. As the gas is used commercially in lighting or for other purposes, it leaves the gasometer and it falls and carries the actuatingerod 4 in the opposite direction and carries the cup with it until one-half its open bottom is over the opposite opening 52, when its load is discharged and produces more gas to take the place of that that is being used. The cranks 46 and 47 are used as follows: If it is desired to give the carbid in hopper 2 a start or to assist it in feeding, spring-plunger 4a is drawn and crank 47 is used as a crank by moving it up and down, moving stirrer 4, which causes the hopper 2 to feed freely. When the crank 47 is thus operated, crank 46 is not disturbed, as the rod 4 rotates freely in its opening in crank 4G. Lever 46 is used separately from lever 47 by freeing spring-plunger 4a and using 46 in making any adjustments necessary with the trough-like member 9 that may be desired, thus using crank 46 as a crank, for which it Was intended.

IrIavin01 now described my invention, so

that thosbe skilled in the art may know how 5 during operation.

ros

to make and use the same7 What I desire to secure by Letters Patent isl. In a gas-machine a feeder for the generator consisting of a shelf or bracket having unobstructed openings through it a bottomless cup or bucket arranged to be slid back and forth over the shelf or bracket, said cup having a partition dividing it into a plurality of compartments, the bottomless compartments eing arranged to register With said openings in the shelf at predetermined times; means for sliding the cup back and forth over the shelf; all so arranged and operating that When the cup is slid across the shelf or floor one at least of itscompartments will register With an unobstructed opening in the shelf and discharge its load into the generator While the other compartments will rest on the imperforate portion of the shelf and not dump its load until the bucket is moved oppositely over the shelf substantially as described.

2. In an acetylene-gas machine a feeder f for the generator consisting of a bracket or fioor having predetermined unobstructed openings through it a moving bottomless l bucket having a partition dividing it into a plurality of pockets and means for moving l 1 said bucket back and forth across said ioor so as to present each pocket in predeter-,l

mined order over an opening in said floor;

and having means for supplying said bucket with carbid at prearranged times substantially as described.

3. A feeder-operator for a gas-machine consisting of a compound revoluble rod one end of which enters the feeder in proximity to the point of exit of the carbid; a lever carried by the rod and in connection With a movable bracket; a crank attached to the rod whereby it may be rotated having a recess and a spring-plunger operating in said recess; a second crank carried loosely on one portion of said compound rod and also tightly affixed to the other portion of said rod and operatively connected with the bell of the gasometer and arranged so that as the bell rises or falls the compound rod will be rotated and the bucket moved and so arranged that either portion ef the rod may be revolved independently of the other portion or be revolved as one continuous rod substantially as described.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing Witnesses.
